Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cyclone dust separating apparatuses, including multi cyclone systems, are inadequate in completely removing minute dust particles from air due to insufficient rotary force and separation efficiency.
Innovation Solution
A multi cyclone dust separating apparatus with improved design features, including a first cyclone unit and a second cyclone unit with cyclones arranged along the inner circumference, a cover unit with air guide paths to enhance rotary force, and a dust collecting unit to collect separated dust, where the second inlet of each cyclone is lower than the first inlet, increasing the rotary force and separation efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional cyclone dust separating apparatuses are used, then the structure is simple, but they fail to completely remove minute dust particles due to insufficient rotary force
Solution Approach 1:
The cyclone dust separating apparatus is divided into a first cyclone unit for preliminary separation and a second cyclone unit with multiple smaller cyclones for fine dust removal. This segmentation allows each unit to be optimized for its specific function, with the second cyclones having smaller diameters to generate higher rotary force for minute dust particles, while maintaining overall system manageability through modular design
Solution Approach 2:
The patent introduces a vertical dimension to the cyclone arrangement by positioning the second cyclones at different heights and orientations around the first cyclone. The second cyclones are arranged in multiple levels (upper and lower rows) with different inlet orientations, creating a three-dimensional dust separation system that enhances rotary force generation through varied airflow paths and heights
2Force
If the second inlet of each cyclone is positioned lower than the first inlet, then the rotary force of air drawn into second cyclones is increased, but the device complexity increases
Solution Approach 1:
The patent applies different inlet positioning strategies to different cyclone units based on their specific functions. The first cyclone has its inlet at a standard height for general dust separation, while the second cyclones have their inlets positioned lower to maximize rotary force generation. This local differentiation optimizes performance for each unit's specific role without unnecessarily complicating the entire system
Solution Approach 2:
The second cyclones are nested around the first cyclone in a compact arrangement, with their lower inlet positions integrated into the overall structure. The multiple second cyclones are arranged in concentric patterns at different heights, creating a nested configuration that maximizes space utilization and rotary force generation while maintaining structural coherence
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The apparatus effectively separates and collects minute dust particles by increasing the rotary force of air drawn into the second cyclones, enhancing dust collection efficiency and addressing the limitations of existing systems.
Implementation Method 1
a first cyclone chamber utilizing centrifugation to separate dust particles from air that is externally drawn in
Implementation Method 2
a plurality of cyclones arranged along an inner circumference of the housing so that minute dust particles may be separated by centrifugation from air that is drawn in from the first cyclone unit
